#ExplanationThe chemical formula
represents a compound made up of sodium (Na) and chlorine (Cl). The number 3 in front of the formula is called the coefficient. It indicates the number of molecules of the compound. The subscript 2 after Cl denotes the number of chlorine atoms in one molecule of the compound. The symbol Cl represents the element chlorine. The total number of chlorine molecules in the compound can be calculated by multiplying the coefficient by the subscript. In this case, 3 (the coefficient) times 2 (the subscript) equals 6.#Answer
3 - coefficient
2 - subscript
6 - total \# molecules of chlorine
- element symbol
